How to get historical data of Futures and options

I tried to fetch historical data of equity using its ISIN. But how can I get it for options chart like nifty and such?

For all Upstox API Services, the instrument_key can be obtained from the Instruments file. You can access this file by visiting the following link: Upstox API Documentation - Instruments.
